I just recently purchased a second processor for my Tyan Tiger MP (S2460) Mainboard and I cannot get the system to boot with it in. (2x AthlonXP 1800+) I know the XP's aren't validated for SMP usage, but I am not exactly worried about that.
Anyway, I cannot get the system to post. It will hang for a few minutes and then the screen will come on saying that there are 2 processors and 256 ram and then it will hang forever.
I am using a Enermax 465W 2 Fan Power Supply. My System Specs are below.
After making that post I started to compare a few processors I had laying around and I saw that the L5's were different on the 2 new ones then they were on my older ones. This article reinforced it these findings and I closed the last L5 bridge.
